Sir: We wish to thank Drs. Manning and Kane for bringing
to our attention the study by Hirschfeld et al. Their observation
is important: clinical setting will affect the relative rate at which
bipolar disorder is overdiagnosed or underdiagnosed. The study
by Hirschfeld et al., however, raises another variable in this debate
that is seldom discussed but perhaps as important, namely,
the extent to which researchers, in publishing their results, highlight
one set of findings versus another.
